The study deals with 5-axis control machining of workpieces with sculptured surface like impellers. The 5-axis control machining allows complex workpieces to be produced efficiently and accurately. Then, it is of importance to avoid the collision between tool and workpiece due to the arbitrariness of tool attitude. The system developed in the study generates the collision-free tool path for workpieces with sculptured surface, based on the CAD/CAM system employing the solid modeling techniques. As a result, the validity of the system is experimentally confirmed.

The study deals with the general method of generating NC data from collision-free tool path of 5-axis control machining centers. The use of 5-axis control machining centers, capable of machining complicated workpiece shapes efficiently and accurately, is recently increased. Then, it is inevitable to generate collision-free CL data and NC data rapidly. CL data are generated by the main-processor having the collision avoidance procedure between a workpiece and an arbitrary tool shape, based on the solid modeling technique. The post-processor developed in the study can convert CL data to actual NC data, taking account of the structure of machining centers, linearization, feed rate control and spindle rotation control. The main-and post-processors are experimentally found effective.
